Question on Custom Filter of RadGridView

[dttanh]

I have created a customized filter control which using usercontrol as a content, 
i have followed by this link to do this : http://blogs.telerik.com/blogs/posts/10-01-22/how-to-customize-radgridview-s-default-filtering-control-with-attached-behaviors-silverlight-amp-wpf.aspx. But at runtime, i cannot find Popup to close this filter. Then also  i created a usercontrol with popup, but when clicking on filter of grid, this filter did not show up. How can i implement this?

Hello,

Inside the filtering control you know the respective column. So here is one possible approach:

private void Button_Click(object sender, RoutedEventArgs e)
{
    var headerCell = this.column.DataControl.ChildrenOfType<GridViewHeaderCell>()
        .Where(hc => hc.Column == this.column)
        .Single();

    headerCell.ChildrenOfType<FilteringDropDown>().Single().IsDropDownOpen = false;
}

I have attached a sample project that demonstrates one possible approach.
